wardly and thus causing a tendency to leak andalso affecting undesirably the appearance of the roof. Another object of the invention is to provide shingles shaped so as to expedite the laying of the shingles on the roof.

()f the accompanying drawings Fig. 1 is a plan view of a plurality of shingles, as they appear when assembled, embodying features of my invention; Fig. 2 is a bottom view of several assembled shingles; .and Fig. 3 is a plan view of a single shingle as it is cut and formed from the sheet I In forming roof coverings with shingles it is desirable to provide a pleasing appear-. once for the roof and to accomplish this consideration niust be given to the appearance of v the shingles after theyare laid rather than tothe appearance of the individual shingles; and the shingles should be made and laid'so as to maintain this pleasing. appearance against the inroads of rain, wind, age, sunli ht, and so on.-.- While the general shape 0 the shingles which I have invented may be modified more or less, yet

laid, substantially a square .or diamondshaped figure and particularly one which approaches a hexagon, having some of its corners eliminated by straight edges. I also prefer to have the corners instead of the edges" extending longitudinally and transversely of the roof, as indicated in Fi 1.

is appearance is arrived at by laying the shin les -with one corner extending downwar y; and at the same time the exosed or lap rtion of the shingle may be Focked down b; turning this corner under an underl ing shingle. But revision must be made or edges under which this corner may be turned and also care must be taken to prevent leakage. I provide for these various features in the following manner:

" The individual shingle comprise a body 22 which has the general shape of a parallelogram, or diamond, preferably a square.

These shingles when assembled are laid in horizontal rows with the adjacent corners 11 substantially in contact. In order to prevent leakage the shingles of each row are staggered with reference to the shingles of the adjacent rows and the shingles of the upper rows over-lap'theadjacent edges of the under rows so muchv as may be deemed desirable. That is the edges 25 of a shingle in one row over-lap the edges 13 of the two ad'acent shingles in the next lowerrow. In

or er to lock down the exposed portion ofeach shingle the lower corner 24 is folded under the shingle and this corner is slipped under the edges 25 ofthe two adjacent un der-lying shingles. In order to accomplish this m an efiective and easy manner I form ofl'sets or shoulders 21 in the edges 25 of the under-lying shingles and the 5 corner 24 passes under the two adjacent edges 21 as indicated. In this mannerzthe laps are permanently locked down and leakageis avoidedby the over-lapping of the upper shingles on the lowershingles. 7

By this arrangement also a pleasing diamond-shaped figure is produced, but with edges 18 instead of corners. And as theseedges are formed by the turning of the corners, and with the shoulder 21 enclosed between the corners and. the'body of the shingles, a thick prominent edge 18 is formed which adds materially to the,appearance of the roof, emphasizing the particular figure formed. This turning under of the corners also emphasizes somewhat the edges 25 so the squareor diamond-shaped: shingle a, j

slit along the edge of the body portion 22 and turning under the'strip 23. In other words, the stri s 23 and a corner 24 are all turned under he shingle.. In this manner the shoulders 21 are formed. And in assembling these shingles on the roof, not only is the corner 24' turned-under the shoulders21 of the underlying shingles, but the strips 23 are positioned between the shingle to which they are attached andthe under-1y in shingllaso as to make a much more de nite e go 25, thus emphasizing still more the figures which are formed by the roof.

At the same time the strips 23 tend'toele 'vate the shoulders 21, when the shingles are laid on the roof, so that the corners 24 are more readily slipped under theshouldersi In laying these shingles it is necessary only to true up the lower'row and the shingles of the next row will be properly sitioned as soon as the corner 24 is p aced under the proper shoulders '21. But in order to insure the proper position of the shingles it is desirable also to see that the corners 11 register with the adjacent similar corners, In may be laid truly over the entire roof Without any additional means being used And by having the shoulders 21 elevated as ex plained the laying of the shingles is a simple and rapid process.

I claim as my invention: I A shingle made from flexible composite this manner the shingles shingle material having a body portion, the

hery of which forms substantial l a para lelogram but the two adjacent e ges thereof having ofiset ortions, and the corner formed by said e ges being folded under the body portion of the shingle, the fold thereof forming a straight edge, forming substantially equal angles with the two ad acent sides, each of said edges having a strip integral therewith and also folded under the body portion of the shingle.

h In1 testimony whereof, I hereunto set my NORMAN r. HARSHBERGER.
